So Im driving down the road and decide to open my Waze app. I tell Siri "open Waze" and she says "There appears to be no app named why". This is so frustrating because I try to open Waze through Siri for another 20 mins to no avail. She just doesnt get how to pronounce Waze. I even tried saying "Waaazzz" and still she doesnt open it.

Ah, thanks for this thread! I struggled with Siri and Waze for the past year finally landing on "open w-a-z-e" but since the iOS 7 update I've been having limited luck with that even. I finally decided to Google it and landed here. I tried a couple of the suggestions mentioned above which didn't seem to work, but somehow I finally got Siri to pronounce the name back to me and it came out like "woz" or "was". So now when I say "open woz" it has worked for me every time! Lifesaver when trying to do everything by voice while driving!
